thanks all, but now have a flat battery! so can't have a go at your suggestions, have called out the RAC to see if they can help. Plus the fuel pump has changed noise - much quieter now and switches off after 20 seconds.

Got the mechanics out today - they could not get it started and said it was more then just an air lock. Today the pump is not cutting off ! they don't know what is wrong with the car and do not have the diagnostic equipment to find out - anyone have any ideas?

tried your five accelerator pumps and the engine light came on but car wouldn't start. Can hear the fuel pump (think thats where the noise is coming from) - rear of car ...is that right? noisy for about 1 min then stops. Any ideas?

you're right its 1999 TD5 - just checked log book. Will try your suggestion. cheers

hi there - just joined up and need some help. I own a discovery TD5 1996 and stupidly ran out (I think) of diesel. The car won't start and know its because of an air lock in fuel system. I don't know how to fix it as I am:- 1) female 2) don't know a thing about cars 3) not particularly...
